【摘要】 研究了２０％Ｃｕ＋２％Ｓｎ＋Ｆｅ的青铜包覆铁粉末体烧结行为及特性，并与相近成分的混合粉末体的烧结行为及性能进行了对比。发现青铜包覆铁粉末的烧结行为与混合粉末的烧结行为相反，后者表现为体积膨胀，而前者表现为体积收缩。分析了产生这一现象的机理及相应的性能特点。更多还原

【Abstract】 Abstract The sintering behavior and properties are studied on the Cu Sn broze coated ferrous powder which contains 20%Cu,2%Sn and 78%Fe in this paper, and compared with mixed powder which has the approximate composition. It is found that the sintering behavior of bronze coated powder is contrary to that of the mixed powder. The mechanism is analysed and some conclutions have been drawn.更多还原
